AIR FOR COMBUSTION AND VENTILATION
Unusually tight construction is dened as
construction where:
a. walls and ceilings exposed to the out-
side atmosphere have a continuous
water vapor retarder with a rating of
one perm (6 x 10-11 kg per pa-sec-m2) or
less with openings gasketed or sealed
and
b. weather stripping has been added on
openable windows and doors and
c. caulking or sealants are applied to
areas such as joints around window
and door frames, between sole plates
and oors, between wall-ceiling joints,
between wall panels, at penetrations
for plumbing, electrical and gas lines
and at other openings.
If your home meets all of the three criteria
above, you must provide additional fresh
air. See Ventilation Air From Outdoors,
page 10.
If your home does not meet all of the three
criteria above, proceed to Determining
Fresh-Air Flow For Firebox Location.
Conned and Unconned Space
The National Fuel Gas Code, ANSI Z223.1/
NFPA 54 denes a conned space as a space
whose volume is less than 50 cubic feet per
1,000 Btu per hour (4.8 m3 per kw) of the ag-
gregate input rating of all appliances installed
in that space and an unconned space as a
space whose volume is not less than 50 cubic
feet per 1,000 Btu per hour (4.8 m3 per kw)
of the aggregate input rating of all appliances
installed in that space. Rooms communicating
directly with the space in which the appliances
are installed*, through openings not furnished
with doors, are considered a part of the un-
conned space.
* Adjoining rooms are communicating only if
there are doorless passageways or ventilation
grills between them.
DETERMINING FRESH-AIR FLOW
FOR FIREBOX LOCATION
Determining if You Have a Conned or
Unconned Space
Use this work sheet to determine if you have
a conned or unconned space.
Space: Includes the room in which you will
install heater plus any adjoining rooms with
doorless passageways or ventilation grills
between the rooms.
WARNING: This heater shall
not be installedin aroomorspace
unless the required volume of in-
door combustion air is provided
by the method described in the
National Fuel Gas Code, ANSI
Z223.1/NFPA54, the International
Fuel Gas Code, or applicable
local codes. Read the following
instructions to insure proper
fresh air for this and other fuel-
burningappliances in your home.
Today’s homes are built more energy efcient
than ever. New materials, increased insulation
and new construction methods help reduce
heat loss in homes. Home owners weather
strip and caulk around windows and doors to
keep the cold air out and the warm air in. Dur-
ing heating months, home owners want their
homes as airtight as possible.
While it is good to make your home energy
efcient, your home ne eds to breathe. Fresh
air must enter your home. All fuel-burning ap-
pliances need fresh air for proper combustion
and ventilation.
Exhaust fans, replaces, clothes dryers and
fuel burning appliances draw air from the house
to operate. You must provide adequate fresh
air for these appliances. This will insure proper
venting of vented fuel-burning appliances.
PROVIDING ADEQUATE
VENTILATION
The following are excerpts from National Fuel
Gas Code, ANSI Z223.1/NFPA 54, Air for
Combustion and Ventilation.
All spaces in homes fall into one of the three
following ventilation classications:
1. Unusually Tight Construction
2. Unconned Space
3. Conned Space
The information on pages 8 through 10 will help
you classify your space and provide adequate
ventilation.
Unusually Tight Construction
The air that leaks around doors and windows
may provide enough fresh air for combustion
and ventilation. However, in buildings of un-
usually tight construction, you must provide
additional fresh air.

127029-01A 9
AIR FOR COMBUSTION AND VENTILATION
Continued
1. Determine the volume of the space (length
x width x height).
Length x Width x Height =__________cu. ft.
(volume of space)
Example: Space size 22 ft. (length) x 18 ft.
(width) x 8 ft. (ceiling height) = 3,168 cu. ft.
(volume of space)
If additional ventilation to adjoining room
is supplied with grills or openings, add the
volume of these rooms to the total volume
of the space.
2. Multiply the space volume by 20 to determine
the maximum Btu/Hr the space can support.
________ (volume of space) x 20 = (Maxi-
mum Btu/Hr the space can support)
Example: 3,168 cu. ft. (volume of space) x 20 =
63,360 (maximum Btu/Hr space can support)
3. Add the Btu/Hr of all fuel burning appliances
in the space.
Vent-free replace _________ Btu/Hr
Gas water heater* _________ Btu/Hr
Gas furnace _________ Btu/Hr
Vented gas heater _________ Btu/Hr
Gas replace logs _________ Btu/Hr
Other gas appliances* + _________ Btu/Hr
Total = _________ Btu/Hr
* Do not include direct-vent gas appliances.
Direct-vent draws combustion air from the
outdoors and vents to the outdoors.
Example:
Gas water heater _________ Btu/Hr
Vent-free replace  _________ Btu/Hr
Total = _________ Btu/Hr
4. Compare the maximum Btu/Hr the space
can support with the actual amount of Btu/Hr
used.
_______ Btu/Hr (maximum the space can
support)
_______ Btu/Hr (actual amount of Btu/Hr
used)
Example: 63,360 Btu/Hr (maximum the
space can support)
79,000 Btu/Hr (actual amount of
Btu/Hr used)
The space in the example is a conned space
because the actual Btu/Hr used is more than the
maximum Btu/Hr the space can support. You
must provide additional fresh air. Your options
are as follows:
A. Rework worksheet, adding the space of an
adjoining room. If the extra space provides an
unconned space, remove door to adjoining
room or add ventilation grills between rooms.
See Ventilation Air From Inside Building.
B. Vent room directly to the outdoors. See
Ventilation Air From Outdoors, page 10.
C. Install a lower Btu/Hr replace, if lower Btu/
Hr size makes room unconned.

If the actual Btu/Hr used is less than the
maximum Btu/Hr the space can support, the
space is an unconned space. You will need
no additional fresh air ventilation.
WARNING: If the area in which
the heater may be operated does
not meet the required volume for
indoor combustion air, combus-
tion and ventilation air shall be
provided by one of the methods
described in the National Fuel
Gas Code,ANSI Z223.1/NFPA54,
the International Fuel Gas Code,
or applicable local codes.
VENTILATION AIR
Ventilation Air From Inside Building
This fresh air would come from an adjoining
unconned space. When ventilating to an
adjoining unconned space, you must provide
two permanent openings: one within 12" of the
ceiling and one within 12" of the oor on the
wall connecting the two spaces (see options
1 and 2, Figure 4). You can also remove door
into adjoining room (see option 3, Figure 4 ).
Follow the National Fuel Gas Code, ANSI
Z223.1/NFPA 54, Air for Combustion and
Ventilation for required size of ventilation
grills or ducts.

Provide extra fresh air by using ventilation
grills or ducts. You must provide two perma-
nent openings: one within 12" of the ceiling
and one within 12" of the oor. Connect these
items directly to the outdoors or spaces open
to the outdoors. These spaces include attics
and crawl spaces. Follow the National Fuel
Gas Code, ANSI Z223.1/NFPA 54, Air for
Combustion and Ventilation for required size
of ventilation grills or ducts.
IMPORTANT: Do not provide openings for
inlet or outlet air into attic if attic has a thermo-
stat-controlled power vent. Heated air entering
the attic will activate the power vent.
WARNING: A qualied ser-
vice person must install rebox.
Follow all local codes.
WARNING: Never install
rebox
• in a bedroom or bathroom*
• in a recreational vehicle
• where curtains, furniture,
clothing, or other ammable
objects are less than 36" from
front or 42" from top of rebox;

to rebox. Installing rebox next
to vinyl or cloth wall coverings or
operating rebox where impuri-
ties(such as, but not limited to, to-
bacco smoke, aromatic candles,
cleaning uids, oil or kerosene
lamps, etc.) in the air exist, may
discolor walls or cause odors.
INSTALLATION
NOTICE: The rebox identica-
tion label (including model num-
ber, serial number, clearances,
etc.) is located on a chain under
the bottom refractory.
IMPORTANT: Vent-free gas log heaters add
moisture to the air. Although this is benecial,
installing rebox in rooms without enough
ventilation air may cause mildew to form from
too much moisture. See, page 8.
IMPORTANT: Make sure the rebox is level.
If rebox is not level, log set will not work
properly.
Note: Your rebox is designed to be used in
zero clearance installations. Wall or framing
material can be placed against any exterior
surface on the rear, sides, top or bottom of
your rebox, except where standoff spacers
are integrally attached. If standoff spacers are
attached to your rebox, these spacers can
be placed directly against wall or framing ma-
terials. Use the dimensions shown for rough
opening to create the easiest installation.

from oor, ceiling, and adjoin-
ing wall.
Carefully follow the instructions below. This
will ensure safe installation.
Minimum Wall and Ceiling Clearances
(see Figure 6)
A. Clearances from the side of the replace
cabinet to any combustible material and
wall should follow diagram in Figure 6.
Example: The face of a mantel, bookshelf,
etc. is made of combustible material and
protrudes 3 1/2" from the wall. This com-
bustible material must be 4" from the side
of the replace cabinet (see Figure 4).
B. Clearances from the top of the rebox
opening to the ceiling should not be less
